Abstract: A delivery system for delivering a heart valve prosthesis includes a heart valve prosthesis and a delivery catheter. The heart valve prosthesis includes an anchoring member and an inner valve support, and further includes a radially collapsed configuration and a radially expanded configuration. The delivery catheter includes a handle, an outer shaft, an intermediate shaft, an inner shaft, and a distal tip component. The delivery catheter further includes a delivery configuration. In the delivery configuration, the outer shaft of the delivery catheter is configured to retain a first portion of the anchoring member, the intermediate shaft is configured to retain a first portion of the inner valve support, and the distal tip component is configured to retain a second end of the anchoring member and a second end of the inner valve support each in a radially compressed state.

Abstract: Systems and methods for approximating tissue segments, such as mitral valve leaflets, on a minimally invasive basis. The system includes first and second approximation devices each including a magnetic component and an attachment mechanism. Each device is connected to a target tissue segment by the corresponding attachment mechanism. Upon deployment at a target site, the tissue approximation devices are magnetically attracted to one another, approximating the tissue segments and maintaining the tissue segments in the approximated state.
